TURBINE.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Application filed March 30, 1912. Serial No. 687,532.

To aZZ whom it may concern:

Be it known that we, JULES HIPPOLYTE CORTHESY, Sn, residing at 50Thornhill Houses, Barnsbury, London, England, and Jones HirronrrnCoirrnesv, J12, residing at 72 Hemberton road, Clapham, London, England,both citizens of Switzerland, have invented new and useful Improvementsin and Relating to Turbines, of which the fob lowing is a specification.

This invention relates to the combustion chambers of internal combustionturbines and hasfor its main objects to enable the air for the explosivecharges to be obtained from a continuous supply and fed into acombustion chamber through the passage through which the explodedcharges are projected from the said chamber, without the use of valvesfor preventing the air from passing to the rotor when supplying thechamber, and to eii'cct a thorough mixing of the constituents of thecon'ibustible charges.

According to the invention we provide a chamber having a passage openinginto it which serves both as an inlet for the air for the explosivemixture and for the discharge of the exploded gases against the turbinerotor, the said passage being so formed that the air will pass to thechamber without affecting the rotor and will be cut off from the chamberby each explosion.

In asuitable arrangement for carrying out the invention the chamber isformed circular or approximately circular with walls either straight orcurved in a direction parallel to the axis of the chamber. The combinedinlet and outlet passage is arranged. tangentially to the combustionchamber and is directly connected to the air supply and has a branch oraperture for directing the explosion gases on to the rotor, the saidbranch being arranged at. an acute angle to the main passage but inpractical alincmcn't with. the end of the latter which opens into thechamber, so that when the air is forced into the said chamber it. willflow past the mouth of the branch without entering the latter to anymaterial extent and when each explosion occurs the pressure of theexplosion gases will oppose that of the air and momentarily stop the[low of the latter into the combustion chamber.

The tangential opening serves to direct the air into the combustioncluin'ibcr so that it flows around the latter and forms a kind of vortexwhich materially assists in mixing the air with the gas or hydrocarbonspray.

For scavenging the combustion chamber of the residual gases after eachexplosion an outlet or chimney is provided in such a position that thesaid gases are driven through it by theincoming air for the next charge7 The combustion chamber is provided with a water or steam acket toprevent overheating and such steam or the steam generated therein can beused for propulsive or other purposes.

To enable the invention to be fully understood we will describe the sameby reference to the accompanying drawing, in which Figure 1 is asectional elevation of a combustion chamber of an internal combustionengine constructed according to our invention. Fig. 2 is a sectionalplan thereof with the upper part removed, and Fig. .is a verticalsection on the line 33 Fig. 9.

a is the combustion chamber which is shown in Fig. as being ofapproximately circular form. with the walls straight in a directionparallel to the axis of the chamber. It may, however, be quite circularand the walls may be curved. The said chamber is advantageouslyconstructed integral with a water jacket I) and is provided with a coverc also formed integral with a water jacket d, the said jackets a and (Zbeing closed by covers (2 and f, respectively.

9 is the tangential passage opening into the chamber a and directlyconnected to the air supply passage h which is connected by a pipez'with a suitable pump or compressor, for instance, a rotary aircompressor.

j is the branch of the passage g for directing the explosion gases fromthe chamber a on to the turbine rotor, not shown, the said branch beingarranged at an acute angle to the passage f/ but in practical alinementwith the end. of tho, latter which opens into the said chamber.

Z: is the inlct, for a hydrocarbon oil spray (or a gas supply) for thecombustible mixture the said illlcl bcing prcl'erably arrangedtangential to the chamber (L and so that the spray (or gas) will passtherein and flow tion when air is forced under pressure through thepassage g in the direction-of the arrows, Fig. 2; into the ch mber a itwill flow past the mouth of the branch 55 without entering the latter toany material extent and when each explosion occurs the pressure of theexplosion cases will oppose that of the air and stop t efiowv of thelatter, the

said gases being projected through the branch 2' and on to the rotor soas to the latter.

m is the outlet or chimney with which the chamber a is provided. forscavenging the latter of the residual gases after each explosion, thesaid chimney being arranged at the propel a center of the upper part ofthe chamber so that the said gases are driven out of the chamber by theincoming air for the next charge, which air sweeps around the chaincombustion chamber having a common passage for the inlet of air for theexplosive mixture and for the discharge of the explosion gases, the saidcommon passage being so formed that the air will pass to the combustionchamber in a direction opposite the direction of the outgoing explosiongases whereby the inflow of air will be out ch "from the chamber by eachexplosion.

2. An internal combustion turbine comprising a combustionchamber havinga common passage for the inlet of air for the explosive mixture and forthe discharge of the explosive gases, said chamber being approximatelycircular in form and the air inlet being arranged tangentially thereto.

3. An internal combustion chamber of the kind described, provided with apassage for the inlet of air, a main air passage leading to said inletpassage and a branch passage opening, into the main passage at an acuteangle thereto.

4:- An internal combustion chamber having a common passage for the inletof air for the explosive mixture and for the discharge of the explosivegases,.said chamber being approximately circular in form and beingprovided with a chimney so located with relation to the walls of thechamber, that the air supply to the chamber sweeps around the latterbefore entering said chimney with the residual gases. n

5. An internal combustion chamber of the kind described provided with apassage for the inlet of air, a main air passage leading to said inletpassage, a branc passage opening into the main passage at an acute anglethereto, and a fuel supply passage.
